Hilton Worldwide Inc. had another positive quarter, beating its revenue projection by $110 million and showing growth in most of its markets.

Observers continue to watch the company closely for indications of new businesses lines and major real estate decisions, however, and the second quarter earnings call with Hilton CEO Chris Nassetta shed some more light on a few key projects.

1. The Waldorf Astoria in New York City: This Hilton-owned, 1.6 million-square-foot hotel property is probably the biggest question mark right now in the company's real estate portfolio. The company has said it is seeking potential partners to redevelop the site, though all scenarios involve keeping at least some portion of the building as a hotel. Some analysts have suggested that the company consider turning a large portion of the famous hotel into pricey condos.

Nassetta didn't address that directly, but he did say that any hotel that remains on the site post-redevelopment would have at least 400 rooms. That's 1,000 less than the number of current rooms.

"There are a lot of ways to look at uses where the hotel could be bigger, but not many ways it could be smaller," Nassetta said. How the plan to reconfigure the property will be structured is still under consideration, he said. The company still hopes to outline plans for the Park Avenue building by the end of the year.

2. Hilton's extensive real estate portfolio is staying put, for now: In response to a question about whether the company has considered spinning off its real estate assets into a separate real estate investment trust, Nassetta said he hasn't seen indicators that it makes sense to do so now.

"Doing it now would be treading water at best, maybe even going under slightly, because of cost of doing it...," Nassetta said. "We would need to see relative valuation and multiples that suggest that the parts separated would be greater than the pieces together."

3. Next brand to be in a more affordable space? Hilton has been teasing a couple of new boutique or lifestyle brands since its IPO last December and the company launched one of them, a collection brand called Curio, in June. It looks like the second brand will be in a slightly more affordable space, with Nassetta for the first time calling the forthcoming brand "accessible lifestyle." Hilton may be trying to take on the likes of Marriott's new-to-the-U.S. AC Hotel brand or boutique brands like Kimpton with is next brand announcement.

That new brand is also still on track to launch by the end of the year, Nassetta said, though its development is expected to move more slowly than the Curio brand.

"For our lifestyle brand, gestation will be a little longer, since it will be a little heavier proportion of new builds and major renovations, versus Curio which is almost immediate conversion opportunities," Nassetta said.
